Also, make Exim more robust to bad + data from the Dovecot auth socket. + +TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients. + + When a queue runner is handling a message, Exim first routes the + recipient addresses, during which it prunes them based on the retry + hints database. After that it attempts to deliver the message to + any remaining recipients. It then updates the hints database using + the retry rules. + + So if a recipient address works intermittently, it can get repeatedly + deferred at routing time. The retry hints record remains fresh so the + address never reaches the final cutoff time. + + This is a fairly common occurrence when a user is bumping up against + their storage quota. Exim had some logic in its local delivery code + to deal with this. However it did not apply to per-recipient defers + in remote deliveries, e.g. over LMTP to a separate IMAP message store. + + This change adds a proper retry rule check during routing so that the + final cutoff time is checked against the message's age. We only do + this check if there is an address retry record and there is not a + domain retry record; this implies that previous attempts to handle + the address had the retry_use_local_parts option turned on. We use + this as an approximation for the destination being like a local + delivery, as in LMTP. + + I suspect this new check makes the old local delivery cutoff check + redundant, but I have not verified this so I left the code in place. + +TF/02 Correct gecos expansion when From: is a prefix of the username. + + Test 0254 submits a message to Exim with the header + + Resent-From: f + + When I ran the test suite under the user fanf2, Exim expanded + the header to contain my full name, whereas it should have added + a Resent-Sender: header.
